Just noticed this, cron is constantly maxing out my cpu on Ubuntu under the user sabnzbd. Sabnzbd isn't doing anything active. Stopping Sabnzbd doesn't kill that process.

How do I get to the bottom of what's causing this?

PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND                                                                                                        
 1736 sabnzbd   20   0   76344   8408    752 S 399.7   0.1  20:46.45 cron

Did you try killing the process (kill 1736)? – Andy Dalton Oct 28 '19 at 18:15
Yes, killing the process removes it until reboot. About a minute after reboot it's back to 400% – Bunga Oct 28 '19 at 18:16
Show us the result of crontab -e – Sir Muffington Oct 28 '19 at 19:26
This is the crontab for user sabnzbd
